Abstract

Patente de Invenção de IMPULSOR DE BOMBA DE UM TIPO CENTRìFUGO OU SEMI-AXIAL. A invenção refere-se a um impulsor de bomba de um tipo centrífugo ou semi-anual destinado ao bombeamento de líquidos, basicamente água de esgoto. De acordo com a invenção, o impulsor de bomba compreende um cubo (4) de roda fornecido com uma ou várias hélices (5), cujos bordos (6) de ataque são fortemente chanfrados para trás. A periferia (8) do bordo de ataque é deslocada de 125-195 graus em relação a sua conexão (7) ao cubo (4) de roda.Patent of Invention of PUMP BOOST OF A CENTRIFUGAL OR SEMI-AXIAL TYPE. The invention relates to a pump impeller of a centrifugal or semi-annual type intended for pumping liquids, basically sewage. According to the invention, the pump impeller comprises a wheel hub (4) provided with one or more propellers (5), whose leading edges (6) are strongly chamfered backwards. The periphery (8) of the leading edge is displaced 125-195 degrees in relation to its connection (7) to the hub (4).
